Sending mine back too, i have 3 of them. I've lost so many days struggling with these cards, not recommend to anybody. I should've tested one first before ordering the others.

There is a way to get 8 card running, i mentioned it in my last comment: connect 6 cards to the black pci-e slots and the other 2 to the first white slots. But for my config and dual mining it is unstable with 8 cards: spurious reboots, GPU failures, etc (6 works with no issues). I don't know maybe it works flawlessly with 7amd +6nvideo. Running 6GPUs per board now until I get the other boards.

Hi this is the problem of mobo. This asrock is a really bad.I had this problem before.Just try to clear your bios and disconnect all the cards. Connect your screen to igpu. Inside the bios turn using of igpu on auto. Setup all pcie slots to gen1. Plug your cards to the slots and do not connect to pcie16-the longest port on the mobo.You should be able to boot.But anyway I am facing problem, that this mobo is not able to boot with 10x rx vega 64. With 9x it is fine, but with 10x its just not working...

Trying to set this up for a friend but I am not getting more than 6 detecting in windows or SMOS. tried changing risers and swapping cards around. Seems to be a BIOS issue? I thought the BIOS was set from out the box for mining.

omg.... why people insist that their experiences are the norm? the problem is NOT with the board but with something else.ALL these steps look like typical Skinner's superstitious behavior

zero changes are actually required.My preferences are: in "advanced chipset" and "boot" sections the following: 1) power up on power restore (the only one really important setting for the case of power drops for my remote setup) 2) disable power warning 3) disable full screen logo - because life is random 4) numlock off on boot 5) disable boot failure warning

I probably have two different revisions of the board bios - one older that gives some weird errors when (successfully) booting from USB into Acronis Image 2017 and another one that gives no such errors... still it matters none - all is working just fine....also I'm not sure if it's the board or new amd drivers, but all my cards orders (gpuz, claymore, overdriven) are now the same - which is really nice when having 12 gpus.

Note: Though the order is still sorta weird slots-wise. Normally I'm connecting raisers in the order of the slots, skipping the one to the right of the x16and since amdflash supports only 10 cards I now know that the 11th and 12th GPUs are always in fifth from the right and 7th from the right slots...

Im using win10 anniversary with 8gb ram and m2 ssd (64- barely fits, so lately 128)Normally I do leave next to the right from x16 slot unoccupied, but I noticed no difference in order and number of connected raisers/cards WHATSOEVER, despite some talks here

Disclaimer: I'm using AMD predominantly and maybe there're some issues with Nvidia after all, since I tried to setup 9x1060 paired with two Vegas FE, but it just refused, while 8*1060 + 2*FEs works just fine.

Hello,I had the problem that system freezes at random time intervals while mining when using 10 Nvidia cards on H110 motherboard running on Win10. I was aware of the limit on Win10: 8 nvidia and 5 amd, or other way round so I got information that windows solved that problem in Fall creators update (1709). Unfortunately, my system was running two days and after that it started to freeze again on random time intervals when mining: approximately 2-3 hours. I tested both EWBF and DSTM miner. Has anyone reported that this win update can fix the problem?

"Here is a tidbit of wisdom we gained by using a FLIR handheld Thermal Spectograph on the rig and wiring and why, as mentioned above you need a spare 12v computer fan. (i haven't found this info anywhere on the net so if you are reading this consider yourself ahead in the game)

on the imgur link above i have included pics of the ASUS and Asrock mobos, the red circle you see is the component that can OVERHEAT and can cause long run mining problems. We found it to go over 70C in relative low ambient temp causing the PCIe slot BUSing to malfunction and freeze/hang the system.

Because we are utililsing the cold outside temp to regulate ambient room temp a fan pointed on that component is enough but you might consider installing a small heat sink to go with the fan for better results if you live in warmer environments.
